Syphilis symptoms may vary by stages that can last for weeks, months or even years, and not everyone experiences all possible symptoms. In the beginning, the signs and symptoms may be mild and not as noticeable. Here are the symptoms for the first two stages, which are the most common and contagious2:
Primary stage symptoms:
- One or more sores on your body called “chancres.” These are typically firm, round and painless sores on the genitals, anus, rectum or mouth.
- The sore usually lasts 3 to 6 weeks and heals regardless of whether you receive treatment. Even if the sore goes away, treatment is still indicated.
Secondary stage symptoms:
- This stage starts with a non-itchy skin rash that is rough, red or brown in color and may appear across the body, including the palms of the hands and soles of the feet.
- Large, raised gray or white spots in warm, moist areas (e.g., armpits, mouth or groin).
- Flu-like symptoms: fever, sore throat, swollen glands, fatigue and/or muscle aches.
- These symptoms can come and go for months or years. Without the right treatment, your infection will progress to the latent stage.
- Very often the rash associated with syphilis mimics many other infections and diseases, and the diagnosis can be missed.
The latent stage that follows has no symptoms, but may be causing internal organ damage. Without the right treatment, you will continue to have syphilis.
Finally, there is the tertiary stage, where untreated syphilis can severely damage multiple organ systems and become life-threatening. Read more about the serious health problems that can occur during the tertiary stage.
